Achieving Material Strength in 3D Printing with Titanium and Aluminum Powders

3D Printing with Titanium and Aluminum PowdersThe Ministry of Education and Science of the Russian Federation’s National University of Science and Technology (NUST) conducted research to develop modifiers that help strengthen the stock material for 3D printing of complex aluminum composites for the aerospace industry.

By 3D printing with metal titanium and aluminum, researchers claim they are able to "double the strength of composites obtained by 3D printing from aluminum powder, and advance the characteristics of these products to the quality of titanium alloys.”

Metal 3D Printing: Renaissance in Additive Manufacturing

Metal 3D Printing is undoubtedly the next big thing in the fast-moving realm of 3D printing.

Put simply, it’s a quick and effective process used to create three-dimensional metal parts from a digital file. Using 3D CAD technology, metal 3D printing techniques use binders, lasers and heated nozzles to create products that are robust and boast intricate internal features (channels, undercuts, inner tubes, internal voids). Components that wouldn’t have been imaginable a few years ago are now a reality due to the various industrial applications available for metal 3D printing today.

Metal powder bed design guide

Recently I’ve gotten a notable uptick in emails from engineers asking whether it’ll be cost effective to use metal powder bed fusion to make an existing (but conventionally manufactured) part. The answer is that it’s complicated, and depends largely on whether or not the part fits into the design requirements for powder bed fusion. Nine times out of ten it doesn’t, but in some cases it’s possible to adapt a design to fit - or redesign from the ground up with additive in mind. In order to help other engineers begin this process, let’s review some of the part characteristics and design guidelines for powder bed fusion.
